To @ZZ whom, lim/(ty concern,.- V

Be it known Ythat I, BENJAMIN F. BEE, a citizen of the United States, residing atllarwich, in the county of Barnstable and State of Mas-` sachusetts, have invented a new and useful Centrifugal Pump, of which the following is a specification. l This invention relates to centrifugal pumps; and it has for its objects to provide a pump of cheap and simple construction and adapted to have increased power for elevating o r discharging received water', and which by itsy special construction prevents the formation generally occur in devices of this character, thus adding greatly to the edicieucy of the apparatus. i i

'Other objects and advantages of the iuven tion will appear in thefollowingdescription and the novell features thereofwill he partienlarlypointed outinjtlie claims.`

Referring tothe drawings, Figure 1 is a perspective view of 'a centrifugal pump constructed in accordancewith my invention.'

Fig. 2 is a transverse section. Fig. isa vertical transverse section. Fig. 4 is a detail in perspective of the water-wheel..

Like numerals of reference parts 'in all the gures of the l indicates the baselof the same is provided near its center with a circular water-receiving opening 2, and located upon the base is a disposed around the opening and eccentric with relation, thereto, and at its inner extremity abruptly disposed tocombine with the outer extremity to form an outlet-spout 4. By reason of the spiral disposition, and consequent eccentricity of the wall, the space between said wall and the edge of the opening is gradually decreased from the outlet to the inner end of the' Wall, and thus allows the water greater impulse under the centrifugal impulsion from themeans to be described. At intervals there is secured to the basenear the edge of the opening vertical deectors or blades 5, which in transverse section are curved to agree with the opening in the base and receive and'delect t le discharged water. The wall has bolted thereto, as at 6, a cover indicate like drawings.` casing,- and the 7, and the same is provided with a central countersunk recess 8, having acentral opening 9.

vertical ilange 3, spirally inlet-box 10, having a iiared inlet-spout `11, saidboxbeing. directly under the opening?v 0f lill@ bds@ and adapted to receive and Vcon- 'action of the wheel within the casing, which subsequently discharges the sameunder force.

.nected by a cross-bar 13, having a'bearing 14, concentriewith and vertically top 7, and also vertically above a bearing 15,. formed in the boit 10. In thebearings 14 and 15, andl passing througlrthe opening 9,

' is a vertical shaft 16, which near the bearing close proximity to the vertical curved deflecting-blades 5. l

It desired, three blades may be employed; but I prefer two, as by experience I have -found a much better result is obtained. The water is drawn from the source of supply through. the inlet into the receiving-box y10 and is delivered therefrom through the openrng inthe bottom of the casing to the revolvingdisk and bladesor iioats, which in theirrotary motioncatch the water and throw the same against the vertical deflecting-plates, which receive the same and direct it around the scroll-casing and give it impulse in its proper course toward the delivery-spout 4, previously referred to.

The deilecting-plates additionally serve to sequent impediment to the free expulsion of the water by the wheel.

I prefer to construct shape,

the bladesQO of .L lor with their lower edges laterally rduct the water within the casing under thev I Iprights l2project from .the base at diagofnally-opposite corners, and the twoy are conabove thev opening Quin the-conntersunk recess 8 of the 20,' which blades are of such provided withtlanged ends of the base, and at their outer edgesico'm'e in To the under side of the base is secured anv prevent the formation of eddies and the con- IOO heut to form the ianges 21, which are at right angles to the bodies of the blades, and

these flanges have their side edges opposite,

thos'eportions above the opening2 depressed or inclined, as at 22, so as to move easily and readily grasp the water received therebeneath and: greatly facilitate its? discharge, the water4 belnggiven a revolving or whirling motion by. the revolving floats or blades and is sent tangentially therefrom under a greater impetus than is generally the case.

Having described my invention, what I claim is- 1. In a centrifugal pu1np .thc combination,

`with the case having the vertical inlet-opening eccentrically related with the wall of the case, of the shaft passing through the case and opening, a disk on the shaft, and blades depending from the 'disk over the opening and having laterally-bent flanges at their lower4 tical inlet-opening eccentrically related with the Wall of the case, of the shaft passing through the case and opening, a dat disk on the shaft above said opening, and straight blades'depending from the disk .over the opening and'havng laterally-bent-tlanges'at their lower edges, said flanges overlapping and ex-` tending beyond the edge of the opening and traveling horizontally thereover and having those portions above the openin g downwardly inclined or bont, substantially as specified.

In a centrifugal pump, the combination, with the casing comprising the base, having the circular inlet-opening, and the'spiral vertical wall eccentrically disposed with relation' to the opening and terminating at one side in a dischargespout, and a cover for the case, having an opening, of vertical curved deflecting-plates secured to the base within the casing near to and concentric with the edges lof the opening, a shaft passing through the case and opening, and a .disk mounted onthe shaft and provided with depending blades traveling within said plate and over the edges of said inlet-opening, substantially as Specified.

4. In a pump of the class described, the combination,with the casing comprising the base having the inletopening`, the vertical spiral wall located adjacent to and eccentric with relation to the opening and having the discharge, the cover having the eountersunk recess abovethe opening and provided with an opening, the receiving-box having the inlet y. located below the opening in the base, and the series of vertical transversely-curved deect- 6o ing-plates mounted on the base adjacent to `and concentric with the opening and within the casing, of the opposite standards extending from the base,'the transverse connectingbar having a bearing vertically opposite the openings in the base and cover, anda bearing formed in the bottom of the dischargebox, the vertical shaft mounted in the bearings, the pulley on the shaft above the case, the disk upon the. shaft within the base, and the depending L-shaped blades secured to the disk and having their hosizontal wing portions-traveling over andoverlapping the edge .of the opening in the base andl having the said horizontal portions thereof immediately above the opening downwardly bent, substantially as specified. I

In testimony that I' claim the foregoing asy my own I have hereto affixed my signature in presence of two witnesses. v BENJAMIN F. BEE.
